Question

Resolva as equações abaixo

Answer 1

Resposta:

Explicação passo a passo:

a)

$2x+1+2x+3+2x+5=63$

$2x+2x+2x+1+3+5=63$

$6x+9=63$

$6x=63-9$

$6x=54$

$x=54/6$

$x=9$

b)

$x+2x+70=250$

$3x+70=250$

$3x=250-70$

$3x=180$

$x=180/3$

$x=60$

c)

$(x+5).3-10=80$

$3x+15-10=80$

$3x+5=80$

$3x=80-5$

$3x=75$

$x=75/3$

$x=25$
